WATCH-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 239,167, dated March22, 1881. Application filed December 1, 1880. (Model) To all whom it mayconcern:

Be it known that I, CLARENCE M. HOWARD, of Fredonia, in thescounty ofChautauqua and State of New York, have invented certain new and usefulImprovements in Regulators for Watches; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in regulators for watches; and itconsists in using teeth upon the outer edge of the balancecock for theindicator to catch in, and thus prevent the indicator from being jarredor shaken to one side or the other.

It further consists in making a curved slot through the balance-cock,and having a small pin or projection which extends do wn from the underside of the indicator and projects through this slot and catches in thespring, and thus regulates its throw, as will he more fully describedhereinafter.

Figure 1 is a plan View of my invention. Fig. 2 is an edge view of thesame. Fig. 3 is a vertical section of the same.

A represents the balance-cock, upon which the regulator B is secured inthe usual manner. Secured to the shoulder on this cock is a curvedplate, C, which has a series of very fine teeth or notches made in itsupperedge, and which teeth or notches projectjust far enough above thetop of the cock to allow the regulator B to catch in them. Also securedto this cock is a guide, G, which extends along just over the top of theteeth, and serves to both prevent the outer end of the indicator beingraised up too high and to guide the regulator back and forth in itsmovement. Should it be so preferred, the teeth may be placed upon theunder side of this guide instead of upon the plate, and in that casewill act in the same manner as already described. When the teeth areplaced upon the plate, as here shown, the

indicator presses downward upon them with justsufticient force toprevent the indicator from being shaken orjarred outof position, but notwith sufficient force to prevent the indicator being moved when force isapplied to it. When the outerend of theiinlicatoris slightly raised itfrees itselt'from the teeth and moves without any friction. Should theseteeth be made in the lower edge of the guide, it will be necessary tohave the indicator bear upward instead of downward, and to depress itsouter end in moving it back and forth. 4

Through the top of the cock, at any suita-' ble distance from the hubupon which the indicator moves, is made a circular slot, 0, andprojecting down through this slot is a pin, V, which catches in thespring for the purpose of controlling its throw or movement. This pin issecured directly to the indicator, and being protected or moving betweensolidplates there is no danger of its being bent or injuredin anymanner.

Should it be preferred, the toothed plate and the guide will be made inone solid piece instead of in two separate and distinct pieces, as hereshown, and thus make it easy to adjust into position.

Having thus described my invention, I claim- 1. In a watch-regulator,the combination of a cock, A, having an ott'set or shoulder, with astationary notched or toothed plate. C, secured to the shoulder, and theregulator B, having its outer end extended out over the top of theplate, substantially as described.

2. In a watch-regulator, the combination of an indicator, a notched ortoothed plate, and a guide, the guide and plate being made in either oneor two pieces, substantially as set forth.

In testimony that I claim the foregoing l have hereunto set my hand.
